Round hole, rectangular junction box


Why not use a standard round junction box? They come in several widths and depths, for example

If the space is very shallow, there are round pancake boxes as well

Two safety issues:

It is imperative that a fixture be solidly mounted, so, if it attaches to the box itself, the box must be attached to framing members or an adequate brace. Small round boxes have limited space, so you must be careful about overfilling them with wires and attachment devices. If there is a single cable with two or three wires, you will usually be okay, but pancakes generally cannot handle several cables.

SUPPLEMENT: As to the question about a square box in a round hole, NEC Section 314.21 says

Repairing Noncombustible Surfaces. Noncombustible surfaces that are broken or incomplete around boxes employing a flush type cover or faceplate shall be repaired so that there will be no gaps or open spaces greater than 3mm (1/8 in.) at the edge of the box.

Epithelial tissue comprises one of the four basic tissue types. The others are connective tissue (support cells, immune cells, blood cells), muscle tissue (contractile cells), and nervous tissue. Organs represent various combinations of these four basic tissue types, which thus comprise the entire body. Each tissue type retains its fundamental character wherever it occurs.

For additional introductory exercises, see Ed (The Path Guy)'s Basic Histology Gallery.


The boundary between you and your environment is marked by a continuous surface, or epithelium, of contiguous cells.

The shape of this boundary is complex, continuing unbroken from skin through various orifices and including the many invaginations into the internal organs of the respiratory, urinary, digestive, and gastrointestinal tracts.

Several of the body's organs are primarily epithelial tissue, ...
